Crambe cultivation has expanded in Brazil. The species is a promising alternative for biodiesel production since its seed contain great amounts of oil. Nevertheless, only few studies have focused on the growth and nutritional requirements of crambe cultivated in acidic soils. Thus, this study aimed to evaluate the effects of liming on the growth and nutrient accumulation of crambe cultivated in a Yellow Latosol of medium texture. The experiment was carried out using a randomized complete block design. The treatments consisted of different soil base saturation levels (0%, 20%, 40%, 60% and 80%) with five replications. Plant height, leaf length, leaf width and the number of seeds were evaluated 90 days after planting. The plant material was separated into leaves, stem, seeds and roots, which were oven dried at 70 ºC until constant weight. Analysis of variance was performed, followed by data regression when significant at 5% probability level by the F test. Crambe responded positively to liming in the soil under study at a base saturation of 56.95% as a function of the biometric variables. The increase in the base saturation of the soil to up to 60% promoted a drastic reduction in plant growth and, therefore, in the final grain yield. The decreasing order of the leaf nutritional content at 56.95% base saturation was: N>Ca>K>Mg>S>P>Fe>B>Mn>Zn> Cu.

ABSTRACT Studies on the effect of transplanting methods and NP – fertilizer rates on leaf length of a female date palm offshoot have been conducted over a period of 25 months (September, 2017 – September 2019). The trial was sited at the Date Palm Research Sub – station/ Federal University Dutse (11o50’N, 09o25’E) in the Sudan Savanna ecological zone of Nigeria.  The treatments consisted of two transplanting methods (Direct: detachment of offshoot from the parent palm and directly transplanting into the field, and Indirect: detachment of offshoot from the parent palm and keeping in the nursery for 3 months before transplanting into the field) and five NP fertilizer rates Control (0g N + 0g P), 80g N + 40g P, 160g N + 80g P, 240g N +120g P and 320g N + 160g P) arranged in a randomized complete block design with three replications. Indirect transplanting of date palm through nursery proved more effective than direct transplanting as it produces statistically longer leaves which are an indication of better chances of crop survival, establishment and yield. Rate 320g N +160g P statistically outperformed other rates in the production of longer leaves throughout the sampling periods. Interaction between transplanting methods and fertilizer rates was highly significant in most of the sampled periods except in June and September, 2019. A combination of indirect transplanting method with rate 320g N +160g P that produced longer leaves is recommended for adoption  in the Sudan Savannah ecological zone of Nigeria.

The experiment was conducted in the Dekarhaor of Noagaon village under South Sunamganj Upazila of Sunamganj district during November 2017 to February 2018 to observe the effect of nutrients management on growth and yield of cauliflower hybrids. Two Hybrids namely ShiraGiku (V1) and Rupali (V2), and four combinations of nutrients, viz. (i) recommended rate of N-P-K-S-Zn-B @ 180-80-180-28-4.5-2.1 kg ha-1(F1), (ii) F1 + 25% N-P-K- S-Zn-B of F1 (F2), (iii) F1 – 25% N-P-K-S-Zn-B of F1 (F3), and (iv)  cow dung @ 10 t ha-1 (F4)  was conducted in a factorial randomized complete block design (RCBD) and replicated thrice. Plant height (cm), numbers of leaves plant-1, leaf length (cm) and leaf breadth (cm), and spreading diameter (cm) were collected at 15 days intervals, while the yield data were recorded at harvest. The parameters were significantly varied due to hybrids and fertilizers packages. Higher gross yield (42.52tha-1) was found in Shira Giku and lower (42.12 t ha-1) from Rupali. Higher curd yield of 25.17 t ha-1 was obtained in Shira Giku than Rupali (9.61 t ha-1). The highest gross yield of 44.45 t ha-1 was obtained when the crop was treated with cowdung @ 10 t ha-1 followed by recommended fertilizer rate (F1). The curd yield of 18.19 t ha-1 was obtained with 25% less than recommended fertilizer rate of application (F3). The highest gross yield of 52.93 t ha-1 was obtained in V1F1 combination and the lowest of 30.10t ha-1in V2 F1. Results revealed that the Hybrid ShiraGiku with recommended dose of fertilizer (180-80-180-28-4.5-2.1 kg ha-1N-P-K-S-Zn-B) performed the best in comparison to other treatment combinations.

Postemergence control of Phyllanthus urinaria L. (chamberbitter) in nursery and landscape plantings has been primarily limited to hand-weeding. Prodiamine was evaluated for postemergence control of chamberbitter and phytotoxicity to containerized ornamentals. On 20 June 1995, prodiamine at 0, 1.68, 3.36, or 6.72 kg a.i./ha was applied over-the-top to immature chamberbitter growing in 3.8-L containers of established Buddleia davidii Franch. `White Bouquet' Cuphea hyssopifolia HBK. `Desert Snow', Lantana camara L. `Irene', and Lantana montevidensis (Spreng.) Briq. `Lavender Weeping'. Weed-free checks were included. Applications were made with a compressed air backpack sprayer. There were four replications per treatment placed in a randomized complete block design by species. Plants were established and maintained on a container bed under full sun and overhead irrigation. Growth of and phytotoxicity to the ornamentals species, and percent coverage and number of chamberbitter, were recorded periodically for 14 weeks after treatment (WAT). Chamberbitter shoots were harvested for dry weight analysis 14 WAT. Prodiamine provided some postemergence control of chamberbitter. However, Cuphea and both Lantana species exhibited leaf distortion and/or delayed flowering.

Ramadiana S, Hapsoro D, Yusnita Y. 2018. Morphological variation among fifteen superior robusta coffee clones inLampung Province, Indonesia. Biodiversitas 19: 1475-1481. This study aimed to characterize morphological variation among fifteensuperior robusta coffee clones in Lampung Province. The fifteen clones consisted of four clones released by the Indonesian Coffee andCocoa Research Institute (ICCRI), i.e. ‘BP 409’,‘BP936’, ‘BP939’, ‘SA 237’, together with eleven superior coffee clones selected byfarmers from Tanggamus District (‘Tugino’, ‘Wanto’, ‘Biyadi’, ‘Komari’, ‘Wardi’, ‘Wariso’) and from West Lampung District (‘TuguKuning’, ‘Tugu Hijau', ‘Tugu Biru', ‘Tugu Sari', ‘Lengkong'). Fifteen qualitative and seven quantitative morphological characters wereevaluated in a randomized complete block design with three replicates for each clone,each replication consisted of two plants. Fromeach plant, four samples were taken from four sides of the plant (north, south, west, and east). It was found that while somemorphological characters exhibited negligible variation among clones, there were significant differences between clones for othercharacters. The characters that did not differ significantly between clones were: shapes of leaf base and leaf tip; petiole color; leafvenation pattern; fruit disk shape; ripe-fruit color; and stipule shape. The characters that varied between clones were shape of leaf lamina(elliptical vs. lanceolate); fruit shape (round vs. oval); and shape of leaf margins. Morphological variation was also observed in somequantitative characters: canopy diameter; tree height; stem diameter; leaf length; leaf width; petiole length; stipule length; and number ofprimary branches.

<em>The estimated value of genotype variability, phenotype variability, environmental variability, and heritability have an important role in breeding activities of tea</em> <em>in order to create the superior varieties. The objective of this study was to investigate the phenotypic performance, genotype and phenotype variation, and heritability value of nine genotypes of tea. The study was conducted at Pemandangan block, Tambi Plantation Unit,  Wonosobo, Central Java, from April 2013 until April 2014. The Randomized Complete Block Design (RBD) with nine treatments and three replications was used in this study. The 9<sup>th</sup> of treatments consisted of 2 genotypes of tea resulting from a cross (GMB 3 and GMB 4), 2 introduced genotypes (TRI 2024 and TRI 2025), and 5 local genotypes resulting from selection (Cin 143, Kiara 8, RB 3, Tambi 1, and Tambi 2). The results showed that the genotype of GMB 3 more higher than other genotypes in pecco length, leaf length, leaf width, length of leaf stalk, and length of leaf internodes characters, whereas Tambi 2, GMB 3, and GMB 4 more higher in fresh weight of P+2 and P+3. The production of fresh shoot of GMB 4 more higher than the other genotypes, but not significant with GMB 3 and RB 3. The leaf length and fresh shoot production characters has a wide of genotype and phenotype variability, whereas the high of heritability value were found in all characters observed. The selection based on leaf length and fresh shoot production characters will be effective because both characters have a high genotypes variability and heritability.</em>

The excessive use of agrochemicals in agriculture has been causing irreversible environmental impacts, from this point of view, organic farming appears as an economically viable alternative to minimize these impacts. So, the objective of this work was to evaluate the effect of different types organic fertilizers in the development and production of coriander harvested at different epochs. The experiment was conducted during the period from August to October 2016, in an area of the experimental farm of University of International Integration of Afro-Brazilian Lusophony. The experimental design was a randomized complete block design, in a 5 &times; 4 factorial scheme, consisting of five organic fertilizers and four harvesting epochs (28, 35, 42 and 49 days after planting-DAP) and five blocks. The variables stem diameter, plant height, root size, number of leaves, leaf length and productivity were evaluated. All the analyzed variables responded significantly by the F test, either for the qualitative factor, fertilizer sources, or the quantitative, epochs of evaluation. Regarding the cultivation epochs, when the first evaluation period (28 DAP) was compared with the last (49 DAP), it was verified that the variables presented linear responses over time, with increases of 34.4% for height , 29.5% for stem diameter, 37.07% for root length and 64.44% for production. In relation to the fertilizer sources, in general, the cattle manure provided a greater growth and production of the coriander plants, being therefore the most suitable for the cultivation.

The coloured cotton crop is the best agroecological alternatives for farmers in semi-arid of Northeasthern region. Cultivation of BRS Verde cotton has been a success on productivity in this region. The practice of monoculture in cotton crop has caused loss of soil quality over the years. The organisms present in the soil are sensitive to changes of land use and management. They are excellent environmental bio indicators, representing important tool to evaluate impacts on ecosystems. In this context, the aim of this research was to evaluate the abundance and diversity of edaphic macrofauna under different management systems in the cotton crop. The design was a randomized complete block design with four replicates with five treatments in 5 collection seasons. The plots consisted of 8 lines spaced 1.0 x 0.30 m for all crops. Three PROVID traps were distributed to capture soil organisms, totally 12 samples/treatments. We identified taxonomic groups, density of organisms, ecological indexes of diversity and wealth of groups. In view of the results, we concluded that the cotton + maize consortium favoured increase of individual’s abundance and richness of faunistic groups. This cotton + maize consortium showed to be a promising alternative for better management and sustainability of the system. We also showed that soil macrofauna is a good indicator of soil quality in different cotton growing systems.

A field experiment was conducted at the farmer’s field of Sutiakhali, Mymensingh Sadar Upazilla, Mymensingh, during the period from April, 2009 to March, 2010 to investigate the effect of organic fertilizers along with half chemical fertilizers on the growth, bulb and flower yield of tuberose cv. single. The experiment consisted of four different sources of fertilizers viz., (i) recommended chemical fertilizers @ 400, 300, 300 and 100 kg ha-1 of urea, TSP, MP and gypsum, respectively; (ii) vermicompost @ 5 t ha-1 along with half of chemical fertilizers; (iii) poultry litter @ 20 t ha-1 along with half of chemical fertilizers and (iv) cowdung @ 20 t ha-1 along with half of chemical fertilizers. The experiment was laid out in a randomized complete block design with three replications. Results revealed that plant height, leaf number plant-1, leaf length and breadth and number of side shoots plant-1, bulb production plant-1, bulb length, bulb diameter and bulb yield both per plant and per hectare, rachis length, spike length and diameter, number of florets spike-1 and flower yield both per spike and per hectare were greater in organic fertilizers along with half chemical fertilizers than absolute use of chemical fertilizers. The highest bulb and flower yield both per plant and per hectare were recorded in poultry manures followed by cowdung. The bulb and flower yields were higher in poultry manures might be due to increased side shoots number, bulb size and flowers plant-1. In contrast, the lowest bulb and flower yields were recorded in chemical fertilizers due to production of fewer side bulb and flowers plant-1.DOI: http://dx.doi.org/10.3329/jesnr.v4i2.10135J.

Nowadays, Orchids are one of the most commercial products in flower markets. One of the propagation methods for Cymbidium is using old pseudobulbs that are thrown out after flowering period. This research carried out using standard Cymbidium back-bulbs based on randomized complete block design with 5 treatments in 3 replications. The trial traits were leaf length, root length, leaf number and root number that were studied for 180 days. The results show that minimum length of root was significant under different growth beds. The minimum percent of rooting was observed in pure sand treatment. The maximum length was observed in pure perlite. The shortest of leaves were gained in perlite + sand treatment and the maximum leaf length was observed in pure perlite treatment. The maximum average of root percent was seen in pure perlite treatment.
